将java方法转换为C＃.NET（verifysign） [英] Translate java method to C#.NET (verifysign)

问题描述

你好



我有一个应用程序用文件.cer和.key签名，但当我尝试用证书文件验证标志时



这是Java中的代码



public static String verifySign（String cerPath，String toVerify，String sign）{

字符串resultado = null;

布尔值blnResultado = false;

try（InputStream cer = new FileInputStream（new File（cerPath）））{

CertificateFactory cf = CertificateFactory.getInstance（X.509）;

证书证书=（X509Certificate）cf.generateCertificates（cer）.iterator（）。next（）;



final签名签名= Signature.getInstance（SHA256withRSA）;

signature.initVerify（cert.getPublicKey（））;

signature.update（toVerify.getBytes（UTF-8））;



blnResultado = signature.verify（Base64.decodeBase64（sign。 getBytes（UTF-8）））;



} catch（异常） e）{

e.printStackTrace（）;



}

if（blnResultado.equals（布尔。 FALSE））{

resultado = new String（Firma Incorrecta）;

} else {

resultado = new String（Firma Correcta ）;

}

返回结果;

}



我尝试过：



我尝试在C＃中做同样的事情，我试图找到其他方法来验证我的应用程序生成的签名。

Hello

I have an application to sign with file .cer and .key, but when I try to validate the sign with only certificate file

This is the code in Java

public static String verifySign(String cerPath, String toVerify, String sign) {
String resultado = null;
Boolean blnResultado = false;
try (InputStream cer = new FileInputStream(new File(cerPath))) {
CertificateFactory cf = CertificateFactory.getInstance("X.509");
Certificate cert = (X509Certificate) cf.generateCertificates(cer).iterator().next();

final Signature signature = Signature.getInstance("SHA256withRSA");
signature.initVerify(cert.getPublicKey());
signature.update(toVerify.getBytes("UTF-8"));

blnResultado = signature.verify(Base64.decodeBase64(sign.getBytes("UTF-8")));

} catch (Exception e) {
e.printStackTrace();

}
if(blnResultado.equals(Boolean.FALSE)) {
resultado = new String("Firma Incorrecta");
} else {
resultado = new String("Firma Correcta");
}
return resultado;
}

What I have tried:

I try to do the same thing in C# and I try to find other ways to verify signature generated by my application.
